1. An electronic apparatus comprising:
a detection unit configured to detect an orientation of a body including an acquisition unit; and
at least one memory and at least one processor which function as:
an acquisition unit configured to acquire information about a user's line-of-sight to a screen; and
a control unit configured to perform control to execute an eye tracking calibration, based on the acquired information about the user's line-of-sight,
wherein the control unit performs control to
acquire first orientation information indicating a first orientation of the body and a first line-of-sight information about the user's line-of-sight, of a case where a first eye tracking calibration display is displayed on the screen;
acquire second orientation information indicating a second orientation of the body and a second line-of-sight information about the user's line-of-sight, of a case where a second eye tracking calibration display is displayed on the screen; and
cause, in a case where the second orientation information is different from the first orientation information, the screen to display a predetermined display that prompts the user to change the orientation of the body to the first orientation.
